Abstract

L'invention concerne un circuit de libération de charge comprenant au moins un circuit de commande photosensible (10), chaque circuit de commande photosensible (10) étant connecté à au moins un circuit de pixel. Chaque circuit de pixel comprend un circuit de décharge (20) connecté au circuit de commande photosensible (10), ainsi qu'un premier condensateur (C1) qui est connecté au circuit de décharge (20) et qui est configuré pour stocker un signal de pilotage d'affichage. Le circuit de commande photosensible (10) est configuré pour commander les circuits de décharge (20) pour qu'ils soient activés dans un état dans lequel une source de rétroéclairage du dispositif d'affichage est éteinte de façon à libérer une charge résiduelle du premier condensateur (C1), et commander les circuits de décharge (20) pour qu'ils soient désactivés dans un état dans lequel la source de rétroéclairage du dispositif d'affichage est allumée de façon que le circuit de pixel commande le dispositif d'affichage pour qu'il effectue l'affichage.
